Chapter 3 – Using Your Wireless
Modem
Changing the GPRS Band
All MultiModem GPRS-F4 wireless modems support quad band (850/1900/900/1800 MHz). In reality, they operate
like dual, dual-band modems. In other words, they can be configured for 850/1900 or 900/1800 MHz; they do not
auto-seek the local area frequency.
Build Options
The GPRS-F4 wireless modems can be ordered with a default band of 850/1900 MHz or 900/1800 MHz.
850/1900 MHz – The wireless modem defaulting to 850/1900 MHz is identified with F4 in the product ordering
number. Example: MTCBA-G-F4. This build option is most commonly used in North American.
900/1800 MHz – The wireless modem defaulting to 900/1800 MHz is identified with F4-ED in the product ordering
number. Example: MTCBA-G-F4-ED. This build option is most commonly used in Europe.
Changing the GPRS Band
If for any reason, such as changing the geographical area in which you use your modem, you want to change the
band, you can accomplish it by using the +WMBS AT Command.
Steps for Changing the GPRS Band
You must use a terminal application such as HyperTerminal in order to enter the AT Command.
1. To open HyperTerminal, click Start. Then select Programs > Accessories > Communications. Then
click HyperTerminal.
2. When the command window opens, type AT+WMBS=<Band><Param>. Press Enter.
For <Band>. Enter the option you desire:
4 = Dual-band mode 850/1900MHz
5 = Dual-band mode 900/1800MHz
For <Param>, enter the option you desire:
0 = The modem will have to be reset to start on the specified band(s). This is the default.
1 = The modem restarts immediately on the specified band(s).
Example: AT+WMBS=4,0. Press Enter.
Phone Number for the Wireless Modem
•
•
Every wireless modem will have its own unique phone number.
The wireless modem’s phone number may simply be told to the subscriber or be on the SIM or both.
Wireless provider implementations may vary.
Examples of Useful AT Commands
A Note About HyperTerminal
In order to verify signal strength and roaming status, you must use a terminal application such as HyperTerminal. To
open this program in Windows XP, go to Start > All Programs > Accessories > Communications >
HyperTerminal. Other Windows operating systems have similar paths to HyperTerminal. See your system’s online
Help if you cannot find it.
A Note About AT Commands
AT commands can be used to operate, configure, and query your modem. A reference guide to the GPRS commands
is included on the MultiModem CD and on the Multi-Tech Web site.
The following two commands let you query signal strength and roaming status.

Establishing a Circuit-Switched Data (CSD) Connection
A Circuit-Switched Data Connection (CDC) makes the wireless modem work similar to a regular analog modem.
You must have CSD service in order to make a CSD call. Note that your wireless provider charges airtime usage
for these connections.
Note: Your cellular provider charges airtime usage for these connections.
Establish a Connection: Using HyperTerminal or a terminal application, you can establish a CSD
connection by entering the following command: ATD<phone number>
Notes:
• The phone number you are calling is entered between the displayed
brackets. Do not type additional brackets. For example, type only ATD
8585551212. 8285551212 is typed between the brackets.
• This command tells the modem to inform the wireless network that you are
initiating a CSD modem call. If you are dialing to another modem, the
remote modem should answer and a connection between the two modems
will be established. If you include a semi-colon (;) at the end of the dialing
string, the modem will instead initiate a Voice call to the phone number
dialed.
Disconnect:
Type: +++
Wait about two seconds to see an OK response.

Chapter 3 – Using Your Wireless Modem
Internet Access
Internet access can be setup in Windows Dial-Up Networking (DUN) of the computer that the wireless modem is
serving. Setup procedures will vary according to the type of wireless service provider used. To access Dial-Up
Networking on your PC, go to Start > Settings > Network Connections.
•
For GSM-without-GPRS, a circuit-switched data connection is used. The user can set up DUN to
make a conventional V.32 modem connection to any terminating modem at the other end. The phone
number specified in DUN can be one supplied by the wireless service provider or another phone
number related to a different dialup modem service (e.g., a dialup modem service phone number from
any commercial or private dialup network).
•
For GSM-with-GPRS, a single DUN number is generally used by all of a wireless provider’s
subscribers throughout its area of coverage; regional, nationwide, continental, etc. Rather than being
a literal phone directory number, as in conventional DUN, this is a code that gives the modem Internet
access.
Connecting to the GPRS Network for Internet Access
After you have inserted the SIM card and the modem is ready for use, you can establish an Internet connection
through a Windows dial-up session.
Note that your wireless provider will charge you for data usage.
Requirements
• One Multi-Tech wireless GPRS modem
• The GPRS modem should have an active SIM card and must have GPRS services
• The modem must be getting a proper signal and be showing a network registration through the wireless
provider’s network
• A PC running Windows Vista, XP, or 2003 with the Multi-Tech drivers installed for your particular model
Notes:
• The following instructions are for Windows XP SP2 and Windows 2003. Every PC may have slight
differences which may cause the instructions to be different. Use these instructions as a guide to help you
understand what is required to set up an Internet connection through your wireless service provider for all
operating systems.
• Cellular providers provide Internet services as part of your service plan. Multi-Tech recommends that if
you plan on using large amounts of data, to sign up for an unlimited data service plan with your provider.
Multi-Tech Systems, Inc. will not be responsible for any charges on your cellular bill. If you have any
questions about billing, service plans, service charges, etc., please contact your provider for more
information.
Set the Access Point Name (APN) into the Modem’s Properties on Your PC
In order for your GPRS wireless modem to connect to your provider’s network, you must tell the modem the
Access Point Name (APN) to which it will connect. The APN is a server name that your account is setup on
with your provider. Your APN will be given to you by your provider. Here are some well-known APNs:
• AT&T: PROXY, or INTERNET, or PUBLIC
• T-Mobile: INTERNET2.VOICESTREAM.COM, or INTERNET3.VOICESTREAM.COM, or
WAP.VOICESTREAM.COM
• Rogers AT&T of Canada: INTERNET.COM
Steps for Setting the APN

Chapter 4 – Troubleshooting and Frequently Asked Questions
Frequently Asked Questions
Which providers can I use?
• Two major providers are T-Mobile and AT&T.
Does this modem support High-Speed Circuit-Switched Data (HSCSD)?
• No, our GSM/GPRS modems do not support HSCSD.
The modem is answering, but seems to not be doing anything?
• The modem is answering in voice mode.
• If you are trying to make a data call, make sure the account has CSD service. You will also need the data
number (separate number from the main phone number that is provided by the provider).
I am trying to make a data connection by dialing from my wireless modem to an analog modem. Why does
the analog modem answer and send tones, but never connect?
• To make a data call you must use the ATD<number> command.
• Make sure the account has CSD service.
How do I get the voice portion to work so I can talk to others using the wireless modem?
• You will need a cable that has the speaker pins connected to a speaker and microphone.
• We have a “Y” cable that splits out to a RJ9 connector that can be used to plug into the receiver of a
handset.
• ‘ATD<number>;’ will originate a voice call.
How do I make an Internet connection to my dial-up ISP?
• Make sure you have CSD service.
• Create a dial-up connection to the ISP’s access number, then use your account username and password
and choose the wireless modem as the device.
How does faxing work?
• GPRS modems support Class 1 and Class 2 Group 3 faxing.
• You will need fax services setup on your account. You should receive a separate phone number for fax just
like voice and data, and you must call the fax number for the modem to receive a fax.
• You will also need fax software (we do not have working software). WinFax Version 10 has been tested with
success.
I can’t make outgoing calls. I just receive a NO CARRIER response.
• Make sure the antenna is connected and SIM is inserted correctly.
• Check signal and registration: ‘AT+CSQ’ (10-31 is good), ‘AT+CREG?’ (0,1 is registered & 0,5 is roaming).
• Check NO CARRIER reason with ‘AT+CEER’. Look up error code in Reference Guide.
The modem will not answer.
• To have modem autoanswer, set modem with ‘ATS0=1’ and ‘AT&W’ to store the setting.
• Send ‘ATA’ to the modem once the RING is indicated on the terminal screen.
• You may need to set modem to ignore DTR, ‘AT&D0’, if you aren’t providing DTR.
I am trying to make a GPRS connection using a Windows dial-up session. It connects and then immediately
disconnects.
• Make sure the APN is configured in the modem correctly (The APN is provided by the provider).
• Check the APN with ‘AT+CGDCONT?’ To make sure it is correct.
• If no APN is inserted, then insert the correct APN using the command ‘AT+CGDCONT=1,”IP”,”<APN>”’ with
HyperTerminal or add it into the “Extra Initialization Commands:” in the modem’s properties.
• Make sure the APN is correct for your account.
When I try to establish a GPRS connection using Windows dial-up I get an error: “Hardware Failure”.
• Check the modem to make sure it is installed and can be queried in the modem’s properties.
• Make sure the com port is not being held by another application. Look for the TR light indication. If it is on,
most likely another application is holding onto the port.
• Make sure the dial-up connections maximum speed matches the modem’s properties maximum port speed.
• Try rebooting the PC.
What is the maximum amount of characters I can use to send an SMS message?
• Supports up to 160 characters maximum.
• In PDU mode using 7-bit, the modem still supports 160 characters, but in 8-bit the modem will support only
70 characters.

Chapter 4 – Troubleshooting and Frequently Asked Questions
After changing the +CNMI, +CSCA, or +CSMP command values, the modem doesn’t store them.
• When changing these command values, you must use the +CSAS command to store the changes.
How do I send an SMS message to an email account?
• When sending an SMS message to an email account, you must use a designated routing number that will
tell the SMS server to route your message to an email account. Here are the numbers that we are aware of
at this time:
AT&T = “0000”
T-Mobile = “500”
Here is an example of how to send an SMS message to an email account:
